Any Good TCP/IP Book Out There?

does anyone know of a good programing book for tcp/ip, lang c++. i have a basic understanding for the osi model along with c++ in gerneral. is there a good step by step, a book that will hold my hand, through the process of writing programs that use tcp/ip? i'm looking to writing my own program that will ping address, or string of address. i've made my own program that will create a batch file, that when run, will ping a string of ip address, that creates a *.txt file on the results. very tedious looking throught the txt file to see which hosts are alive. i will post my source code for further understanding.

#include <iostream>

using std::cout;
using std::cin;
using std::endl;
using std::cerr;
using std::ios;
using std::endl;

#include <fstream>

using std::ofstream;

#include <cstdlib> //edit prototype

int main()
{

int ipa; //first segment of ip address
int ipb; //second segment of ip address
int ipc; //third segment of ip address
int ipd; //fourth segment of ip address
int ipmax; //the number to stop on
int range; //qusetion if the range is correct
int end; //asks if user wants to start over or end

//ofstream constructor opens file
ofstream outClientFile( "ping.bat", ios::out );

cout << "file that will show the results of the ping.\n";
cout << "You will enter the ip address one segment at a time.\n";
cout << "Don't include the periods.\n\n\n";

ipab:
cout << "Enter first segment number:";
cin >> ipa;

if (ipa > 255)
goto ipa255;

if (ipb > 255)
goto ipb255;

goto ipd255;

iprange:

if (ipmax <= ipd)
goto ipless;
if (ipmax > 255)
goto ipmax255;

outClientFile <<"Ping.exe -n 1 -l 10 "<<ipa<<"."<<ipb<<"."<<ipc<<"."<<ipd<<">>ping.txt"<<endl;
}


question:
cout << "\n\nTo start program over type -1-, or to end, type -9-.\n\n";
cout << "WARNING! STARTING THE PROGRAM OVER WILL OVERWRITE THE PING.BAT FILE!\n";
cin >> end;

if ( end == 1 )
goto begin;

if ( end == 9 )
goto end;

if (end != 1 && end != 9)

in no way do i entend to use my knowledge, or any knowledge gained, for malicous intent.

Paralyse, other members may help you better than I do.

I have one comment tho... While SOMETIMES it is really necessary to use goto to simplify the code and/or to speed up the runtime process, I don't see goto is needed here. It even (I think) complicates your code.

Try using if ... else ... blocks. I see you have used while, that's good. Then you can use system() to execute ping.exe directly. Have fun!

Peace always,

thank you for your comments and insight. i used the goto command becuase i wanted to have all the error messages all together. i guess i'm lazy. maybe i'll tweek it when i get a good tcp/ip book, if anyone knows of one

do u need the book for Network Programmig?

this is considered to be a good book for Unix network programming, i personnaly have not started reading it, but will start soon.

Author Stevens, W. Richard.
Title : UNIX network programming / W. Richard Stevens, Bill Fenner, Andrew M. Rudoff.
Imprint : Boston, MA : Addison-Wesley, c2004
i hope this helps u mate, if u need more information let me know we can search it out.

Hands down the best book about TCP/IP is TCP/IP Illustrated by W. Richard Stevens.

I can recommend all three volumes. The last volume is more programmers based and talks about ways to setup services and using the protocols in C.
